Growth of Single Crystals in the Bi-Sr-Ca-Cu-O System Using KCl as a Flux

Abstract

Single crystals of Bi 2 Sr 2 CaCu 2 O x having good crystallinity were successfully obtained. Nitrates of Bi, Sr, Ca and Cu were used as raw materials. Specially prepared solute calcined at low temperatures (below 500°C) were used with a KCl flux. The solvation of this solute to the KCl flux proceeded very smoothly. Single crystals having smooth surface were extracted from the KCl flux. Fundamental electrical and magnetic properties of the crystals have been investigated.
